About this study

Official title: Combination Therapy With Tirzepatide, Empagliflozin and Pioglitazone Versus Standard Therapy in Newly Diagnosed Type 2 Diabetes: a Multi-center Randomized Controlled Trial

The goal of this clinical trial is to learn the efficacy of combination therapy with tirzepatide, empagliflozin and pioglitazone versus standard therapy in newly diagnosed type 2 diabetes. The main objectives to achieve are:

  1. To compare efficacy of the triple combination therapy against standard therapy in achieving type 2 diabetes remission in patients newly diagnosed with T2DM.
  2. To compare the effects on β-cell function and glycemic control of the triple combination therapy against standard therapy in patients newly diagnosed with T2DM Researchers will compare drug new triple combination therapy with tirzepatide, empagliflozin, and pioglitazone to standard therapy (metformin based treatment) to see if new triple combination therapy works better in achieving type 2 diabetes remission.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Diabetic remission rate

    Diabetic remission rate at 6 months after discontinuation of medication (percentage of patients with HbA1c <6.5% at 6 months after discontinuation of medication)

    Measured: 6 months after discontinuation of medication

Secondary outcomes (14)
  1. Diabetic remission rate

    Diabetic remission rate at 3 and 12 months after discontinuation of medication and the time of diabetic remission

    Measured: 3 and 12 months after discontinuation of medication

  2. Time required to achieve glycemic goal

    The time required to achieve glycemic goal(FBG <6.1mmol/L, 2h PPG <8.0mmol/L or HbA1c#6.5%)

    Measured: 6 months of medication

  3. EQ-5D-5L questionnaires, quality of life

    EQ-5D-5L questionnaires, assessment of quality of life. The EQ-5D-5L essentially consists of 2 pages: the EQ-5D descriptive system and the EQ visual analogue scale (EQ VAS).

    The descriptive system comprises five dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. Each dimension has 5 levels: no problems, slight problems, moderate problems, severe problems and extreme problems.

    The EQ VAS records the patient's self-rated health on a vertical visual analogue scale where the endpoints are labelled 'The best health you can imagine' and 'The worst health you can imagine'. The VAS can be used as a quantitative measure of health outcome that reflects the patient's own judgement.

    Measured: At baseline, at 6 months of medication treatment, and at 3, 6, and 12 months after discontinuation of medication

  4. Incremental cost per additional remission

    Incremental cost per additional remission at 6 months after discontinuation of medication

    Measured: 6 months after discontinuation of medication

  5. HbA1c

    HbA1c level at baseline, at 6 months of medication, and at 3, 6, and 12 months after discontinuation of medication

  8. Blood C-peptide level

    Fasting and 2-hour postprandial C-peptide level at baseline, at 6 months of medication, and at 3, 6, and 12 months after discontinuation of medication

    Measured: At baseline, at 6 months of medication, and at 3, 6, and 12 months after discontinuation of medication

  9. Pancreatic β-cell function

    HOMA-B at baseline, at 6 months of medication, and at 3, 6, and 12 months after discontinuation of medication

    Measured: At baseline, at 6 months of medication, and at 3, 6, and 12 months after discontinuation of medication

  13. Incremental cost per additional improvement in Time in Range (TIR)

    Incremental cost per additional improvement in Time in Range (TIR) at 6 months of medication treatment, and at 6 months after discontinuation of medication

    Measured: 6 months of medication treatment, and at 6 months after discontinuation of medication

  14. Incremental cost per QALY gained

    Incremental cost per QALY gained, derived from EQ-5D-5L assessments at baseline, at 6 months of medication treatment, and at 3, 6, and 12 months after discontinuation of medication

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Group A (triple combination intensive therapy group) and Group B (standard therapy group) in people with Diabetes Mellitus, run by Sun Yat-sen University at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 20 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: opening soon, as of the sponsor's last update on 9 Jun 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Hai Li, MD, PHD (+86-15920362668, lihai8@mail.sysu.edu.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Diabetic remission rate (time frame: 6 months after discontinuation of medication). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 9 Jun 2026.
